SSI offers two families of ultrasonic liquid level sensors - Fluid-Trac® and Acu-Trac®.

Whatever your tank or storage container depth and profile, SSI probably has an ultrasonic liquid level sensor for you.Our ultrasonic liquid level sensors use ultrasonic technology to generate a high-frequency sound wave to measure the time for the echo to reflect off of the target and return to the ultrasonic liquid level sensor. The distance from the ultrasonic liquid level sensor to the fluid is calculated based on the speed of sound and the profile programmed into the sensor.
